Solution Overview

Problem

Existing gutter brooms are inefficient in cleaning surfaces due to non-modular design, leading to increased packaging and delivery costs, and require complex assembly and maintenance, which can damage surfaces and increase operational costs.

Innovation Solution

A modular gutter broom design with removable bristle strips and carriers, allowing for customization and easy assembly and maintenance, using recyclable materials to reduce environmental impact and operational costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a non-modular design is used for gutter brooms, then the structure is simpler, but the packaging and delivery costs increase

Engineering Contradiction:

ImprovestructureVSAvoidpackaging and delivery costs

Core Design Contradiction:

Device complexityVSLoss of substance

Solution Approach 1:

The gutter broom is divided into modular components including a mandrel, multiple carriers with bristle strips, and individual brush members. Each carrier can be independently assembled and disassembled, allowing for compact packaging and reduced delivery costs while maintaining structural integrity during operation

Inventive Principle:

Principle #1Segmentation

2Device complexity

If a non-modular design is used for gutter brooms, then fewer components are needed, but assembly and maintenance become more complex

Engineering Contradiction:

Improvenumber of componentsVSAvoidassembly and maintenance

Core Design Contradiction:

Device complexityVSEase of manufacture

Solution Approach 1:

The brush is segmented into multiple independent carriers that can be easily attached and detached from the mandrel. Each carrier contains bristle strips that can be independently replaced, simplifying assembly and maintenance operations while using a reasonable number of standardized components

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The carriers are designed as universal components that can be used in different positions on the mandrel and can accommodate various bristle strip configurations. This multi-functionality reduces the total number of unique parts needed while facilitating easy assembly and maintenance

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Device complexity

If traditional gutter brooms are used, then the structure is simpler, but surface damage increases during cleaning

Engineering Contradiction:

ImprovestructureVSAvoidsurface wear

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

Different bristle strip configurations can be selected for different carriers based on the specific cleaning requirements of various surface areas. Softer bristles can be used for delicate surfaces while more aggressive bristles are used for tougher areas, optimizing cleaning effectiveness while minimizing surface damage

Inventive Principle:

Principle #3Local quality
